Natural Alkaloids and Heterocycles as G-Quadruplex Ligands and Potential Anticancer Agents.
G-quadruplexes are four-stranded nucleic acid secondary structures that are formed in guanine-rich sequences. G-quadruplexes are widely distributed in functional regions of the human genome and transcriptome, such as human telomeres, oncogene promoter regions, replication initiation sites, and untranslated regions. Many G-quadruplex-forming sequences are found to be associated with cancer, and ...
متن کاملSyntheses and DNA binding of new cationic porphyrin-tetrapeptide conjugates.
Recently cationic porphyrin-peptide conjugates were synthesized to enhance the cellular uptake of porphyrins or deliver the peptide moiety to the close vicinity of nucleic acids. DNA binding of such compounds was not systematically studied yet. We synthesized two new porphyrin-tetrapeptide conjugates which can be considered as a typical monomer unit corresponding to the branches of porphyrin-po...
متن کاملDesign, synthesis and biological evaluation of Ciprofloxacin- peptide conjugates as anticancer agents
Cancer has emerged as a leading cause of death throughout the world. Peptides are a novel class of anticancer agents that can specifically target cancer cells with low toxicity to normal tissues and thus, offer new opportunities for future cancer treatment. On the other hand, Ciprofloxacin, an antibiotic, also known to its anticancer property for enabling cell cycle arrest and creating double s...

متن کاملDiazonia- and tetraazoniapolycyclic cations as motif for quadruplex-DNA ligands.
It is demonstrated that even unsubstituted cationic ligands, namely the known diazoniadibenzochrysenes (, ) and the so far unreported tetraazoniapentaphenopentaphene (), stabilize quadruplex DNA upon association; the ligand exhibits essentially the same affinity towards the quadruplex as does 5,10,15,20-tetrakis(1-methyl-4-pyridyl)-21H,23H-porphine, however, with a significantly higher selectiv...
